[0005] Furthermore, two groups of positioning holes are provided on both sides of the top of the positioning frame, and the moving area of ​​the casters of the mobile robot is limited by the positioning frame.

[0006] Furthermore, a slide groove is provided at the bottom of the infrared sensor, and the casters of the mobile robot can be sensed by the infrared sensor.

[0007] Furthermore, a slide plate is provided on the top of the caster fixing plate, and the casters of the mobile robot can be fixed by the caster fixing plate.

[0008] Furthermore, a protective cover is provided at the detection end of the signal detector, and the signal positioning of the mobile robot can be performed through the signal detector.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] The utility model transmits a signal to the control terminal via an infrared sensor, and the control terminal controls the caster fixing plate 4 to fix the casters of the mobile robot, thereby ensuring that the casters remain stable during movement, reducing shaking or swaying caused by unstable movement, providing more accurate caster positioning, and reducing the risk of accidental sliding or falling off, thereby improving the operational safety of the robot and improving the fixing effect of the device on the casters of the mobile robot.

[0015] In order to make the technical means, creative features, objectives and effects of the utility model easy to understand, the utility model is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0016] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings.

[0017] Example 1

[0018] like Figure 1-3 As shown, a mobile robot caster positioner includes a positioning frame 1, an inclined plate 2 and an infrared sensor 3. The inclined plate 2 is provided on the right side of the inner side of the positioning frame 1, two groups of infrared sensors 3 are provided on the inner side of the positioning frame 1, two groups of caster fixing plates 4 are provided on the inner side of the infrared sensor 3, an electric telescopic rod 5 is provided inside the positioning frame 1, and a signal detector 6 is provided on the top of the electric telescopic rod 5.

[0019] Description of working principle: The staff installs the positioning frame 1 to the specified position, and uses the electric telescopic rod 5 to drive the signal detector 6 to rise and fall to the top. The signal detector 6 can capture and analyze the signal from the mobile robot in real time, so as to realize its accurate position information, which is conducive to precise positioning, so that the mobile robot can avoid collision or unnecessary contact with other objects, and help the mobile robot improve its positioning accuracy. When the mobile robot moves to the specified position, the infrared sensor 3 on the inside of the positioning frame 1 will sense the casters of the mobile robot. When the infrared sensor 3 senses that the casters of the mobile robot have reached the specified position, the infrared sensor 3 will transmit a signal to the control terminal, and the control terminal controls the caster fixing plate 4 to fix the casters of the mobile robot, so as to ensure that the casters remain stable during the movement, reduce the shaking or swaying caused by unstable movement, provide more accurate caster positioning, and reduce the risk of accidental sliding or falling off, thereby improving the operational safety of the robot and improving the fixing effect of the device on the casters of the mobile robot.

[0020] The positioning frame 1 is mainly used to limit the moving area of ​​the casters of the mobile robot. When selected, two groups of positioning holes are provided on both sides of the top of the positioning frame 1.

[0021] The inclined plate 2 is mainly used to limit the movement of the casters. When selecting, a conventional one can be selected from the existing technology according to the needs.

[0022] The infrared sensor 3 is mainly used to sense the casters of the mobile robot. When selected, a slide groove is provided at the bottom of the infrared sensor 3.

[0023] The caster fixing plate 4 is mainly used to fix the casters of the mobile robot. When selected, a slide plate is provided on the top of the caster fixing plate 4.
